Mathematical model of the development of the wedging crack in the disturbed material

Abstract

The article represents the numerical solution of the problem of the increasing wedging crack in the disturbed material. Solution of problem was achieved by the method of discontinuous displacements. Analytical dependences of the stress intensity factors of the first type on the normal displacements of the crack was determined.
